To find the mass of the block of ice, we can use the equation:
Weight = Mass × Acceleration due to gravity
In this case, the weight of the block of ice is given as 520 Newtons. The acceleration due to gravity on Earth is approximately 9.8 m/s².
So, let's plug in the given values into the equation:
520 N = Mass × 9.8 m/s²
To solve for mass, we can rearrange the equation:
Mass = Weight ÷ Acceleration due to gravity
Mass = 520 N ÷ 9.8 m/s²
Calculating this gives us:
Mass ≈ 53 kg
Therefore, the correct answer is C. 53 kg.
The mass of a block of ice that weighs 520 Newtons on Earth is 53 kg.
Therefore, the answer is option c
The weight of an object can be calculated using the formula weight = mass x acceleration due to gravity. In this case, the weight of the block of ice on Earth is given as 520 Newtons. We can use the formula to solve for mass by rearranging it to solve for mass: mass = weight/acceleration due to gravity. Assuming the acceleration due to gravity on Earth is 9.8 m/s², we can calculate the mass as follows:
mass = 520 N / 9.8 m/s² = 53 kg
Therefore, the mass of the block of ice is 53 kg.

Explanation:
We are given this equation and we need to find the value of :
(1)
Firstly, we have to clear :
(2)
Applying Natural Logarithm on both sides of the equation (2):
(3)
(4)
According to the Natural Logarithm rules, so (4) can be written as:
(5)
Finally:
A rigid, 2.50 L bottle contains 0.458 mol He. The pressure of the gas inside the bottle is 1.83 atm. If 0.713 mol Ar is added to the bottle and the pressure increases to 2.05 atm, what is the change in temperature of the gas mixture?
The initial temperature of the gas is
wrong 137
⇒ 122 K. correct on E.D.G
B) It gains protons and becomes positively charged.
C) The number of positive and negative charges can be the same.
D) It has to be a metal.
E) There is no change in the distribution of the charge in the object.
Answer: Option C: The number of positive and negative charges can be same.
A substance is said to be polarized when there is non-uniform distribution of electric charge. When there gain or loss of electrons, ions are formed. It is not necessary that polarized object is metal. For example, Water is polarized. The oxygen atoms have partial negative charge and hydrogen atoms have partial positive charge.
